While the main component of the HVC is tracing the collimated jet, the broad component is often associated with the base of the jet or a disk-wind and the NLVC with a slow-moving compact disk-wind or a photoevaporative wind from the disk [1]}, [2]}. In the case of RU Lup, the different nature of such components has been recently confirmed by the spectro-astrometric analysis of [3]}. Here the authors showed that the HVC and the broad component come from the extended jet and base of the jet, respectively, whereas the NLVC originates from a very compact (\(\lesssim \,\) 8 au) MHD disk-wind.
